Idle Suitable mechanism 14 comprising a fixed positiongbar, a set screw, and'a returning spring is Figs. 6 to 10 are detailsectional views provided to return the shift key and type are to initialposition.

In operation the striking mechanisms are in normal position as shown inFig. 2. When it is desired to print the letter B on the type bar 4, forinstance, pressure is borne-down on the key button 3 of the key lever 2which assumes the position shown in full lines in slot 10, to be shiftedby the pin 9 on the type bar 4 into the position shown in Fig. 7. The

pin and slot connection 9 and 10 between the i type bars 4 and 4' merelyacts to shift'the printing. position of the type bar 4 when the two typebars are moved relatively longitudinally b their res ective key levers.

By pressing both the key buttons 3 and 3 simultaneously as exemplifiedin full lines in Fig.8, both of the type bars 4 and 4' will movetogether toward striking position. This is due to the fact that type bar4 carrying the .pin 9 is not shifted relatively to the slotted type bar4 hence both of the typev .bars will move forwardly at the same time andat the same rate of speed. However,,the

single letter which is a. combination of the lettersG-J on the type bar4' is made more than type high with respect to the letter B on theadjacent type bar 4 so that it will project outwardly a little furtherthan the letter B, thereb allowing only 'the combina tion character. Jto be printed. Thepin 9 maintains its position in the slot 10, as shownin Fi 8. The letter B will be slightly removed rom the platen as shownin Fig. 9 and the combination letter G-J will be in striking positionagainst the platen as shown in Fig. 8. However, when both of the keys- 3and 3' are pressed, and the key button 3 is pressed sli htly in advanceof the key 3' as shown in Fig. 10, the type bar 4 will be slightly inadvance of the type bar 4 which makes up for the prominence of thecombina-' tion character G-J, and both the combination character and thecharacter B will strike the platen simultaneously and print both thecharacter B and the combination character GJ, Fig. 3. During thisoperation the pin 9' will move slightly longitudinally in the ofprinting position with respect to the platen and the figure 1 will be inprinting contact as shown in Fig. 4, thus enabling the character 1 to beobtained with the same striking mechanisms.

If the shift key 6 and both keys 3, 3 are all depressed simultaneouslyor the shift key depressed and followed by the simultaneous depressionof both keys 3, 3' the figure 1 and the letter S will print as shown inFigs. 4 and 10 thus enabling a different combination of printedcharacters to be obtained.

By operatively interconnecting the two type bars or printing membersthereby causing one to shift relatively to the other, more letters canbe printed with a given number of keys than heretofore known to beprinted in machines of this character.

In Figs. 11 to 19 which is a selected embodiment of the invention in amodified form 20 designates a striking mechanism comprising the keylever 21, key button 22, and type bar 23 which is operated through anintermediate link 24. A shift key 25 operatively connected to a type barcomb 26 shifts all the type bars in relation to the platen 27 in amanner well known in the art. A universal bar 28 is adapted to operatethe platen roller 27, Fig. 12, and a stop bar 29 limits the upwardmovement of the key levers. The type bar 23 of the striking mechanism 20is provided with a pin 30 which is adapted to engage a slot 31 in theadjacent type bar 23 which is an operative part of the strikin mechanism20. Suitable mechanism 33 and 34, Fig. 12, is operably connected to thekey lever and type bar to return the same to initial position.

The striking mechanisms are in their nor mal position as shown in Fig.12 and for the purpose of illustration the same printing characters willbe used for reference as.employed in explaining the device shown in igs.1 to 10. ,When it is desired to print "the letter B the button 22 ispressed as shown in full lines in Fig. 13 allowing the type bar 23 tomove forward to normal printing position; the pin 30 is free to move itsrequired distance in the slot 31 without in any way affecting orshifting the type bar 23'. The type bar 23 will move inwardly in normalprinting position as shown in Fig. 13 and the letter B will be printed,Fig. 18.

When the key button 22' is pressed to operate the type'bar 23' this typebar will move to the position shown in Fig. 14. As this typebar,carrying the lower letter S is being guided by the pin 30 on thetype bar 23 the type bar 23' will be raised and cause the letter S onthe lower part of the type bar 23' to be printed.

When both of the striking mechanisms 20 and 20 are operatedsimultaneously as shown in full lines in Fig. 15 the type bars 23 and 23of each mechanism will move together while the type bar 23 will be inthe position shown in Fig. 16 with the letterB away from the platen andtherefore not. printed. If both the character B and the combinationcharacter G-J are desired to be printed at the same time, the strikingmechanisms 20 and 20 are both operated with accent on thestrikingmechanism 20 and the key levers.

of each striking mechanism will be inthe position shown in Fig. 17. Thiswill cause the type bar 23 of each striking mechanism to bemovedslightly in advance of the type bar 23' of the other striking mechanismand bring the face of both the character B and the combination characterG-J in alinement so 7 that both of these characters strike the platensimultaneously and are printed.

By pressing the shift key 25, Fig. 12, the

type bar comb 26 will cause the type bars of all the striking mechanismsto be moved on their axes 32 thereby shifting the relative osition ofthe characters in relation totheir ormer or normal printing position onthe platen. When the striking mechanism 20 is depressed its ty bar 23will move forward as formerly, l lt the bottom portion of this type barcarrying the figure 1 will print;

' the letter B being. raised from its normal printing position. If theshift key and both of the striking mechanisms are depressed[simultaneously both of the bottom characters of the respective strikingmechanisms will be printed due to the new rinting posi tion caused bythe operation 0% the type bar comb, Fig. 19.

While Ihave shown the type bars inter- I connected with a pin and slotarrangement,

it is to be understood that a similar arrangement may be made with thekey levers; or instead of just having two characters on each type bar,more may be employed, and

the arrangement of the slot and pin changed to cause more than twoletters to be printed from the same ty bar.

Changes may struction and arrangement of the partswithout departing fromthe spirit of the invention or sacrificing any of its advantages and theright is hereby reserved to make all such changes as fairly fall withinthe scope. of the following claims I claim; 1.
